@BarackObama: Happy Birthday 'Obamacare'

President Obama's re-election campaign, which has been celebrating the Affordable Care Act all week, has officially tweeted a 'Happy Birthday' from the @BarackObama account.

"Happy birthday to Obamacare: two years in, the Affordable Care Act is making millions of Americans' lives better every day," read the message, which was sent by campaign staff not the president himself. (Tweets from Obama are signed -BO)

Note the use of the term 'Obamacare' - which some Democrats have previously considered a pejorative since it is commonly used by Republicans to criticize the law.

"If you're proud of Obamacare and tired of the other side using it as a dirty word, complete this sentence: #ILikeObamacare because…"

At a fundraiser at the Tyler Perry studios in Atlanta last week, Obama also used the term and said he doesn't mind it because it shows he "does care."

"Change is, yes, health care reform," Obama said to applause. "You want to call it Obamacare - that's okay, because I do care."

"That's why we passed it. That is why we passed it - because I care about folks who were going bankrupt because they were getting sick. And I care about children who have preexisting conditions and their families couldn't get them any kind of insurance. And so now we've got reforms that will ensure that in this great country of ours you won't have to mortgage your house just because you get sick."

Obama delivered a similar message in August during a bus tour through the Midwest.
